FRANKFURT—European Central Bank officials decided to look through the volatility in financial markets that occurred in the weeks before the bank's June 3 meeting, the minutes of that meeting showed Thursday, suggesting officials weren't concerned about rising bond yields, weaker equity prices and a higher exchange rate for the euro.

The ECB was prepared to respond if those forces led to weaker growth and inflation, the ECB said in the minutes, but officials didn't see that as necessary.

"It was widely felt that it was advisable for the Governing Council to look through recent financial market volatility," the minutes stated. The ECB broadly agreed that the decline in some financial asset prices was due to a mix of forces, including a firmer economic outlook, some recovery in expectations for future inflation and technical factors, such as poor liquidity in markets.

At a news conference following that meeting, ECB President Mario Draghi reflected this assessment and appeared nonplused by the fluctuations in fixed-income markets that led up to the June 3 meeting.

"We should get used to periods of higher volatility," he said on June 3. "At very low levels of interest rates, asset prices tend to show higher volatility, and in terms of the impact that this might have on our monetary policy stance, the Governing Council was unanimous in its assessment that we should look through these developments and maintain a steady monetary policy stance."

Mr. Draghi's comments added fresh impetus to a sharp selloff in eurozone government bonds that began in late April but paused in May.

Yields on German 10-year bonds surged above 1% in early June, having fallen almost to zero earlier in the year. Investors said the ECB chief's relaxed attitude to the unprecedented volatility in the euro area's benchmark asset gave the green light for further sharp swings.

Still, the ECB's chief economist, Peter Praet, in his presentation to the board, highlighted the need to think about the ramifications of the market volatility on the effectiveness of the ECB's monetary policies. "This might suggest that the ECB is prepared to vary the pace of its asset purchases at least in response to market movements," said Jonathan Loynes, economist at consultancy Capital Economics, in a research note.

Elsewhere, the minutes signaled that ECB officials were reasonably optimistic that the eurozone was on track for a moderate economic upswing and slow buildup in inflation. Consumer prices were up 0.2% on an annual basis last month, far below the ECB's target of near 2%.

Consumer prices had contracted in late 2014 and the early months of this year. That prompted the ECB to announce in January a bond purchase program totaling over €1 trillion ($1.1 trillion) that was launched in March and is due to run at least through September 2016.

"All in all, the euro area economy was seen to be moving in the right direction and inflation was also improving," the minutes stated, adding that this outlook depended on the full implementation of the ECB's stimulus measures.

Officials also highlighted the decisive importance of broader economic reforms and strong tax and spending policies to boost the region's growth potential. "There was no room for complacency," the minutes said.

Although Mr. Draghi's postmeeting news conference on June 3 was dominated by questions about Greece, there was no specific mention of Greece in the meeting minutes, suggesting the topic didn't dominate the discussions.

There was, however, one reference to "prevailing geopolitical risks and continued uncertainty about the outcome of negotiations between one euro-area government and its official creditors were also seen as likely sources of market uncertainty and volatility."
